uname
uname(2) System Calls uname(2) NAME
uname - get name of current operating system SYNOPSIS
#include <sys/utsname.h> int uname(struct utsname *name); DESCRIPTION
The uname() function stores information identifying the current operating system in the structure pointed to by name. The uname() function uses the utsname structure, defined in <sys/utsname.h>, whose members include: char sysname[SYS_NMLN]; char nodename[SYS_NMLN]; char release[SYS_NMLN]; char version[SYS_NMLN]; char machine[SYS_NMLN]; The uname() function returns a null-terminated character string naming the current operating system in the character array sysname. Simi- larly, the nodename member contains the name by which the system is known on a communications network. The release and version members fur- ther identify the operating system. The machine member contains a standard name that identifies the hardware on which the operating system is running. RETURN VALUES
Upon successful completion, a non-negative value is returned. Otherwise, -1 is returned and errno is set to indicate the error. ERRORS
The uname() function will fail if: EFAULT The name argument points to an illegal address. ATTRIBUTES
